N2 - This article presents the degradation rates over 8 years for 3000 photovoltaic (PV) installations distributed across the U.K. The article considers three PV cell technologies, namely, monocrystalline silicon (Mono-Si), polycrystalline silicon (Poly-Si), and thin-film cadmium telluride (CdTe). The available raw data undergoes three key stages: normalization, filtering, and aggregation, before the degradation analysis of the considered installations. This algorithm can be considered as one of the article contributions. Results show that a maximum degradation rate of −1.43%/year is observed for the CdTe type, whereas Poly-Si and Mono-Si PVs have annual degradation rates of −0.94% and −0.81%, respectively. Moreover, this article exploits the monthly mean performance ratio (PR) for all the examined PV sites. The highest PR value of 87.97% is calculated for the Mono-Si PV installations, while 85.08% and 83.55% are calculated for Poly-Si and CdTe installations, respectively.
